Moisture mapping is a crucial step in detecting and preventing moisture-related issues in buildings. Moisture levels in drywall must be monitored closely to ensure the building's structural integrity and occupants' health. This blog will delve into acceptable moisture levels in drywall and explore the critical question: at what moisture level does mold grow in drywall?
The optimal moisture content for drywall ranges between 5% and 15%. This range allows the drywall to maintain its strength and structural stability without absorbing excessive moisture that can lead to damage or decay.
Excessive moisture can cause drywall to soften, sag, or buckle. It can also create an environment conducive to mold growth, which poses significant health risks. Therefore, it is essential to monitor moisture levels in drywall and take measures to address any elevated moisture content promptly.
Mold can begin to grow in drywall at moisture levels as low as 28%. However, the rate of mold growth and the severity of the infestation increase significantly as moisture levels rise.
Maintaining moisture levels in drywall below 28% is crucial to prevent mold growth. This may involve implementing moisture control measures, such as improving ventilation, repairing leaks, and using dehumidifiers in areas with high humidity.
